Abstract

PROBLEM TO BE SOLVED: To improve a function of a passage by making a fire door device composed of a fire door, a door frame and a guide mechanism to horizontally move the door frame adjacent to a fire shutter. SOLUTION: A fire door device A is composed of the fire door main body part 3 to secure an escape passage at fire time, a frame body 4 to rotatably support the door 3 and a guide mechanism 5 slidably suspend/support the frame body 4 in the horizontal direction. Next, the device A is arranged adjacently to a fire shutter 1 to divide a passage by extending the shutter 1 by manually or motor-driving. In this case, the lower end part of the fire shutter 1 is guided by a guide column 2 and the vertical side part on the illustrated left side of the frame body 4. At ordinary time, the door 3 is slidingly moved up to a position overlapping with the wall surface of a building together with the frame body 4. Therefore, at ordinary time, the fire door device can be prevented from hindering a passage by narrowing an effective width of the passage so that the deterioration of a beautifual appearance of the passage can be prevented since superfluous thing does not exist on the passage.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire door provided with a fire shutter in a passage of a building or the like.

[0002]

At a place where a fire shutter is installed in a passage of a building, a fire door is provided adjacent to the fire shutter in order to secure an evacuation route in the event of a disaster. By the way, such fire doors can be very effective in the event of a disaster, but they are only useless in normal times. That is, the fire door provided adjacent to the fire shutter significantly narrows the effective width of the passage, which greatly impedes traffic.

Accordingly, an object of the present invention is to provide a fire door device which does not affect the width of a passage in normal times and does not hinder traffic.

[0004]

An object of the present invention is to provide a fire door apparatus to be installed adjacent to a fire shutter, wherein the fire door is used as a fire door main body and a guide post of the fire shutter. The problem is solved by a fire door device comprising: a frame body rotatably supporting a main body; and a guide mechanism supporting the frame body slidably in a horizontal direction.

[0005] In other words, if the fire door apparatus is constructed as described above, the fire door body can be displaced together with the frame supporting the fire door body, for example, so as to overlap the wall surface in normal times. As a result, the area previously occupied by the fire door even in normal times is opened. That is, the effective width of the passage is not narrowed by the fire door body or the frame. Therefore, the fire door device of the present invention does not hinder traffic in normal times. In addition, when a disaster occurs, it plays a major role in forming an evacuation route, just as in the conventional case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in more detail with reference to FIGS. 1 is an elevation view of a place where the fire door device is installed, and FIG. 2 is a sectional view taken along line XX in FIG. In FIGS. 1 and 2, what is indicated by A is the fire door device of the present embodiment. Although the figure shows a state at the time of a disaster, it can be displaced to a position shown by a dashed line in normal times.

The fire door apparatus A of this embodiment is provided adjacent to the fire shutter 1 as can be seen from FIG. Although FIG. 1 shows the fireproof shutter 1 in a rolled-up state, this fireproof shutter 1 is manually or electrically extended when a disaster occurs and cuts off the passage.
At this time, guiding the lower end of the fire shutter 1
It is a part of a frame, which will be described later, which constitutes the guide pillar 2 and the fire door device A.

The fire door apparatus A includes a fire door body 3, a frame 4 for rotatably supporting the fire door 3, and a guide for suspending and supporting the frame 4 so as to be slidable in the horizontal direction. And a mechanism 5. Of these, the fire door body 3 is shown in FIG.
It can be rotated to the position shown by the two-dot chain line, that is, 90 °. On the other hand, the left vertical portion of the frame 4 has the same cross-sectional shape as the guide column 2 because it serves as a guide column for guiding the lower end of the fireproof shutter 1 as described above. Further, although not shown in detail, the guide mechanism 5 includes a roller disposed at the upper end of the frame 4 and a rail fixed to the building side on which the roller is hung.

When the fire door apparatus is constructed as described above, the fire door body 3 together with the frame 4 supporting the fire door body 3 can be displaced in a normal state so as to overlap the wall surface of the building. Therefore, the effective width of the passage is not narrowed, and does not hinder traffic in normal times. In addition, the appearance is excellent because there is no extra thing on the passage.

[0010]

The fire door apparatus of the present invention does not affect the width of the passage in normal times and does not hinder the passage.
